SPECIFICATION forming part of Letters Patent N0. 429,421, dated June 3, 1890.

Application filed November 15, 1889. Serial No. 330,478. (N model.)

{ This serves to hold said central portion free from the wall when the rack is secured to the To all whom it may concern:

Be it known that 1, CHARLES H. 0011, a citizen of the United States, and a resident of Glenville, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Pipe-Racks, of which the following is a specification, the principle-of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from all other inventions.

The object of this invention is to provide a pipe-rack adapted to support steam or other pipes in proper and relative position.

The primary intention of the invention was Fig. 2 is a front elevation view of the same.

Fig. 3 is a rear elevation view of the same. Fig. 4 is a central longitudinal section taken through the pipe-rack arm, a cross-section of a pipe being shown in position on the rack. Fig. 5 is a transverse horizontal sectional View of the rack, taken on the dotted line of Fig. 2 in the direction indicated by the arrow.

The body A of the rack is made from any suitable metal, and consists of the two longitudinal sides A, two or more pipe-supporting arms B, forwardly proj ectingfrom said body portion, said arms being formed integral with said body portion at suitable intervals throughout its length, said arms corresponding and commensurate with the openings a, formed adjacent and opposite to the same respectively in the rack-body. Transverse connections a are located intermediate of said arms and serve both as base-supports for said arms and also as connections between said side portions. Said connections a at their central longitudinal portion are of concavo-convex form, the convexity being on the side from which project the arms, with the compensatory concavity on the opposite side.

same, whereby less heat from the "pipe is transmitted to the wall on which the rack is hung, and the heat passes to the side portions A, and is thus disseminated over a greater area instead of being concentrated on the central longitudinal portion of the rack. This concavo-convex formation extends a little more than midway up the arms, and here it serves another function namely, by its curved form it serves to greatly strengthen the said arm and prevent the weight of the pipes bending or breaking the same. 1 Each arm B is formed with a forwardly-projecting lower section b and an upwardly-projecting upper section I), such forward projection in the formation of the arm being adapted to permit of the steam-pipe being inolosed between the latter and the rack-body. The arm is widest at its base, and gradually narrows toward its free upper end. The concavo-convex formation of the arm may be designated on its lower side as a rib b projecting for about two-thirds of its length from its base upward, such rib projecting from its outer surface, while a corresponding depression 12 is formed on the inner surface of said portion of the arm. Said rib is widest at its base, where strain falls on the arm, and gradually narrows toward its upper end, where less strength is required for the arm. This strengthening-rib may be struck up by the same operation which punches or cuts out the arm from the rack-body. So, too, the arms may be formed simultaneously, so that the the bent arms B, extending forward from and integral with said parts a, substantially as set forth.

2. A pipe-rack consisting of two longitudinal sides A, two or more forWardly-projecting arms B, and transverse connections a, located intermediate of said arms, said transverse connections respectively having a central longitudinal concavo-convex portion, the concave side of which is opposite to the side from which said arms project, said transverse portions serving both as base-supports for said arms and also as the connections bet-ween said side portions, all of said several parts being formed integral from a single piece of sheet metal, substantially as set forth.

3. A pipe-rack consisting of two longitudinal sides A, located in the same plane, two
